OIL-PRESS.

Specification of Letters Patent.

Patented Dec. 16, 1913.

Application filed March 18, 1913. Serial No. 755,193.

To all whom it may concern:

Be it known that 1, MICHAEL B. GREEN, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented new and useful Improvements in Oil-Presses, of which the following is a specification.

This invention relates to oil presses and more particularly to the mats used in connection therewith.

Various attempts have been made to secure a durable mat which would have the producing qualities of the old hair mat and at the same time eliminate the slow operation necessary with such a type of mat. It has been proposed to use a perforated plate supported upon the bottom of the box but this type of mat has proved ineffective for several reasons, particularly on account of its distortion under Pressure.

It is the object of this invention, therefore, to produce a mat which will avoid the difficulties heretofore encountered and which will have the producing qualities of the old hair mat with considerably greater speed in operation and with a consequent reduction of labor.

Further objects of the invention will appear as the following description is read in connection with the accompanying drawings, which form a part of this application.

Broadly speaking the invention consists in forming a mat of a plurality of grooved bars having ports or channels leading into the grooves from the upper surface and bein so formed as to produce a corrugated ca (e receiving surface.

Figure 1 is an elevation of an ordinary oil press with a number of the boxes in section. Fig. 2 is a top plan view of one of the mats. Fig. 3 is a longitudinal sectional view through the same. Fig. 1 is a detail side elevation of one of the mat bars. Fig. 5 is an end elevation of one of the side bars. Fig. 6 is an end elevation of one of the intermediate bars. Fig. 7 is a sectional view through one of the intermediate bars taken at the base of the corrugation. Fig. 8 is a similar sectional view through one of the side bars. Fig. 9 is a top plan view of a modified type of mat.

To illustrate the invention I have shown an ordinary oil press consisting of a base 1, uprights 2 and a head 3 which receives the thrust of the boxes as they are propelled by the ram, the plunger 4 of which only is shown.

Suspended upon bolts 5 in the usual mannor are the boxes which consist of a plurality of what may be termed base plates 6 corrugated upon their under surface, as shown at 7, and havin depending flanges or guiding strips 8 which encompass the mat 9 of the next lower box. More correctly speaking the box consists of the under surface of one plate, the mat supported upon the next lower plate and the guiding flanges 8. Each plate 6 is provided with an up standing wall or flange 10 which surrounds the mat 9 and is spaced away therefrom so as to confine the oil flowing from the mat and conduct it to a port 11 made through the plate, the oil passing from the top box running into the next lower box and so forth to the bottom plate 12 which is made saucerslji appd to contain a predetermined quantity o 01 Each mat, as shown in Figs. 1 to 8, comprises a base 13 provided with longitudinal channels 14 adapted to receive the mat bars 15 and 16. These mat bars 16 each consist of a longitudinal rib 17 adapted to fit the channels 14 in the base, and an enlarged head 18 which is transversely corrugated on its upper surface, as shown in Fig. 4. The sides of the head taper so as to coact with the adjoining bars to produce longitudinally extending self-clearing channels 19 somewhat larger at their base or exit than at their top or entrance point. These channels communicate with longitudinal ports 20 formed between the bars and between the heads and the upper surface of the base 13. At the base of each corrugation there is formed in opposite sides of the head 18 a self-clearing channel 21 which communicates with the channels 19 and with the longitudinal ports 20.

The bars 15 are similar to the bars 16 except that the channels 21 are formed only upon one side of the head and the corrugations do not extend throughout the width of the head. Also the opposite side of the head is arranged to overhang and rest upon the base 13, as shown in Fig. 1. These bars are also different from the bars 16 in that they are wider at one end than at the other and the base 13 is correspondingly wider at one end than at the other so as to produce a substantially frusto wedge-shaped mat which permits convenient removal of the oil cake at the large end.

Each bar is provided at its ends with a longitudinally projecting lug 22 which is engaged by the rib 23 of the locking plate 24:. There are two of these locking plates one arranged at each end of the mat and both are bolted to the plate 6, as shown. These plates may be reinforced by steady pins 25 which are carried by the base 13 and project into the plate 6, as shown. In this instance, the locking plates serve merely to hold the base down upon the plate and the bars 15 and 16 in position in the base.

In the modification shown in Fig. 9, the base 13 is transversely channeled and the bars extend transversely of the base and thereby produce longitudinal corrugations which extend the full length of the mat, or in other words, to a point adjacent the side edges of the end bars.

With this type of device there is no danger of distortion of the mat as all of the parts are constructed of cold rolled or milled steel. However, should one of the bars become bent or warped it is considerably cheaper to replace the same than to replace the mat plate now in use.

In order to more readilyfree the oil in the cake and to increase the producing qualities of the machine I preferably arrange a series of notches or channels 26 in the flanges or guiding strips 8 so that the oil in the upper portion of the cake or adjacent the bottom of the plate 6 may find convenient exit to the next box below.

What I claim is 1. A mat for oil presses comprising a channeled base, a plurality of bars seated in the channels and having slots therein, said bars constructed to produce oil discharge channels which communicate with the slots.

2. A matfor oil presses comprising a channeled base, a plurality of bars seated in the channels and havingslots therein, said bars constructed to produce oil discharge channels which communicate with the slots and means to hold the bars in the channels.

3. A mat for oil presses comprising a channeled base and bars seated in the channels and constructed to co-act with the base to produce oil discharge passages, said bars having slots to communicate with said passages.

4. A mat for oil presses comprising a channeled base, a plurality of bars having wide heads and narrow longitudinal ribs, the under side of the heads and the walls of the ribs coact-ing with the .base to produce oil discharge passages, said bars having slots extending through the head and in communication with the passages.

5. A mat for oil presses comprising a channeled base, a plurality of bars having wide heads and narrow longitudinal ribs, the under side of the heads and the walls of the ribs coacting with the base to produce oil discharge passages, said bars having slots extending through the head and in communication with the passages, lugs on the ends of the bars and means for engaging the lugs to hold the bars on the base.

6. A mat for oil presses comprising a plurality of bars having wide heads transversely corrugated and narrow longitudinal supporting ribs, said bars having slots in opposite sides of the head arranged in the trough of the corrugations.

7. A mat for oil presses comprising a base, a plurality of bars seated upon the base and having lugs thereon, said bars constructed to produce oil discharge channels and having slots therein to communicate with the channels and means to engage the lugs for preventing the bars from rising off of the base.

8. In combination, a base plate, a base mounted thereon and having channels therein, a plurality of bars seated in the channels and constructed to produce oil discharge channels opening onto the base plate and means secured to the base plate and engaged with the bars for preventing disengagement of the bars from the base and for holding the bars and base upon the base plate.

In testimony whereof I affix my signature in presence of two witnesses.
